Cowboy Bebop (1998)

Set in the year 2071, humans managed to colonize several planets and moons of the solar system, which leaves the inhabitable planet Earth behind. The Inter Solar System Police is assigned to keep peace within the galaxy, which are composed of bounty hunters called "Cowboys."

Carefree and easy-going Spike Spiegel works with his sensible and high-spirited partner, Jet Black - who makes a living through chasing bounties and prizes. Now, they no longer work in pair as additional members join them that they've encountered in one of their adventures - Ein (a Welsh Corgi), Faye Valentine and Edward Wong.
